IPC: B42D15/10
Filed: 1989-04-26
Abstract: PURPOSE:To eliminate a need to adjust the position of an object detecting sensor or a camera at each time of switching the classification of products by controlling the delay time from taking-in of the object detecting sensor output to output of a shutter trigger signal. CONSTITUTION:When the tip of an object 1 to be inspected flowing on a line reaches the position of an object detecting sensor 3, a detection signal 7 is inputted from the sensor 3 to an image processing device 4. The device 4 outputs a shutter trigger signal 8 to a shutter camera 2 to pick up the image of a number part when a prescribed time corresponding to the classification of a product elapses after the input of the signal 7. This picked-up image is subjected to A/D conversion and is taken into a memory and is recognized to inspect the number; and if it is abnormal, an abnormality signal 9 is outputted to a shrink packing machine controller 10. Thus, the product switching work is easily performed in a short time and the number is automatically inspected though there are plural products and they are different in size and number print position.

Title: Digital radio communication system
Inventor: DOUI YOSHIKAZU
IPC: H04B7/24
Filed: 1983-06-15
Abstract: PURPOSE:To suppress the jitter of reproduced digital information by setting the reception system between a master station and a corresponding slave station in an optimum state by the slave station indentification signal before comunication is carried out between the master station and plural slave stations. CONSTITUTION:A master station transmits a carrier wave containing a station indentification signal fB which displays a specific slave station, e.g., station B to all slave stations with a frequency f1 for a fixed period of time while it has no communication with any slave station. The station B detects the signal fB through a BPF and actuates a signal control circuit SC with the detection signal. Then the station B turns on the transmission system and transmits the non-modulated wave of a frequency f2 to the master station. Receiving the non- modulated wave, the master station waits after setting the own reception system in an optimum state.
